Z4 ECU
Hopefully I will be getting a Z4 off a WRX for my UK turbo MY 96 pre facelift Saloon today, any tips on what I should do when fitting and after installation? I understand I will need to use Octane Booster or High Octane fuels, best ones for the car please? 
Will I have to do a reset via the wires under the dash or no? Cheers............

Fitting is easy take the old ecu out and out the new ecu in (the plugs are different sizes so you can work out which one goes where).
The Z4 should work fine with 97 SUL (as prodrive used the same map for their early UK cars) but most people use vpower or tescos99 ron.
Go for a drive with the fuel of your choice (keeping to the speed limits) for ½hour just so the ecu can adjust itself.
I run mine on vpower/99ron and it's fine.
